Mark Divine is a former Navy Seal who now teaches meditation and resiliency to athletes. There is a bit of testosterone in the first few minutes because, well, he's teaching this to weight lifters. But once he gets into the meditation training notice how zen everyone gets. The key is in the exhale and allowing the stress drain out of your body.

"Don't give up in the dark. The sun is going to rise again". ~ Mark Divine

This talk by Dr. Richardson is about Resilience and validating your emotions. "Listen to the strong emotions with discernment".
